Has anyone done a direct comparison between a power 25 and a power 32 with this plane yet?

I spent four hours flying my P-51B on a G32 770kv with a 13x6.5x2 propeller today.
Most of my flying time was at 3/4 to full throttle.
I kept easing it back of full when I noticed I was there.
So I put the 13x8x2 TGS sport prop. back on.
It's there to stay this time.
When I first flew the "B" with the stock recommended setup, I didn't like the performance of the 13X6.5. The 13X8 gave the speed I expected.

A 25 sized motor might fly get the "B" in the air, but I can't see it flying this 6lb airplane with any authority
